Why not do the same again and get some more on the go from seed. It's better to be a bit late with your seeds, than too early, they usually catch up.
One more tip that will help with next years efforts is keep a diary ( now ) of when you start all your seeds, beans, spuds etc. If you are like me you will have forgotten by next year. I don't keep a diary myself, but I know someone who does.
My saviour is a retired teacher who is a fellow allotment holder.
Now he keeps lists of every detail of what, when and where every seed was sown, potted, re-potted and planted out ! All I do is copy him a week or so later .. I know it's cheating, but who cares. He needs organisation and control in his life, whereas I just need an easy life !
